[0048] The outer surfaces of the left and right sides of the installation frame 2 are provided with flow grooves 3 communicating with the interior thereof;

[0050] Further, two screening plates 5 are fixedly connected to the outer surfaces of the two fixed shafts 4;

[0051] Wherein, a mesh plate is provided on the screening plate 5;

[0052] The two sides of the two screening plates 5 away from the two fixed shafts 4 extend out of the left and right outer surfaces of the mounting frame 2 through the flow slots 3;

[0053] The front and rear surfaces of the screening plate 5 are slidably connected to the front and rear inner walls of the mounting frame 2;

[0054] The two fixed shafts 4 are slidably connected to the left and right inner walls of the installation frame 2 away from the outer surfaces of the two screening plates 5 .

[0055] Furthermore, four limiting plates 15 are fixedly connected to the upper surfaces of the two screening plates 5;

[0056] The outer surfaces of the front and rear limiting plates 15 facing each other are slidably connected to the inner walls of the front and rear sides of the mounting frame 2;

[0057] The front ends of the two fixed shafts 4 rotate and penetrate the front surface of the installation frame 2;

[0058] The two sprocket wheels 6 are fixedly sleeved on the outer surface of the two fixed shafts 4 passing through the installation frame 2 .

[0059] Further, the chain 8 is transmission-connected between the two sprockets 6;

[0060] Wherein, the two screening plates 5 are both arranged at an inclination;

[0061] Among them, the two screening plates 5 are arranged in a mirror image;

[0062] Among them, the two screening plates 5 are arranged up and down;

[0063] The fixing block 7 is fixedly connected to the front end of the left fixing shaft 4 .

[0064] Furthermore, the motor base 10 is fixedly connected to the left side surface of the mounting frame 2;

[0065] Wherein, the motor 9 is fixedly connected to the upper surface of the motor base 10;

[0066] Wherein, the support shaft 11 is fixedly connected to the rotating output shaft of the motor 9;

[0067] The mounting block 14 is fixedly connected to an end of the support shaft 11 away from the motor 9 .

[0068] Furthermore, the positioning slide block 13 is fixedly connected to the outer surface of the mounting block 14 on one side away from the support shaft 11;

[0069] The positioning slot 12 is provided on the front surface of the fixing block 7;

[0070] The positioning slot 12 extends backward out of the rear surface of the fixing block 7;

[0071] The front surface of the positioning slide block 13 extends into the positioning slide groove 12;

[0072] Wherein, the positioning slide block 13 is slidably connected with the positioning slide groove 12;

[0073] The flow slot 3 is adapted to the screening plate 5 .

[0074] Furthermore, the metallurgical auxiliary materials that need to be screened are poured into the installation frame 2, and then screened through the two screening plates 5. The mesh size of the upper screening plate 5 is larger than the mesh size of the lower screening plate 5. When the metallurgical auxiliary materials with larger particles roll downward through the two inclined screening plates 5 and flow out of the installation frame 2 through the two flow grooves 3, the metallurgical auxiliary materials with larger particles are screened out, and the two screening plates 5 make the metallurgical auxiliary material particles falling from the installation frame 2 more uniform, and the screening effect and quality are better, thereby increasing the practicality of the screening device.

[0075] Furthermore, by screening through two screening plates 5 with different mesh sizes, the sizes of metallurgical auxiliary materials discharged on the left and right sides are different, and the metallurgical auxiliary materials can be screened in multiple stages, making the screened metallurgical auxiliary materials more practical, thereby increasing the practicality of the screening device.

[0076] Furthermore, when the motor 9 is started, the motor 9 starts and synchronously drives the support shaft 11, the mounting block 14 and the positioning slider 13 to rotate synchronously. The rotation of the positioning slider 13 synchronously drives the fixed block 7 to perform a small reciprocating rotation around the fixed shaft 4 on the left side. Driven by the chain 8 and the two sprockets 6, the two fixed shafts 4 synchronously reciprocate, and then synchronously drive the two screening plates 5 to perform a small rotation around the two fixed shafts 4, thereby driving the metallurgical auxiliary materials of the screening plates 5 to vibrate. Starting the motor 9 can drive the two screening plates 5 to vibrate at the same time, thereby avoiding the metallurgical auxiliary materials from clogging the screening plates 5, making the screening efficiency higher and the screening effect better, thereby increasing the practicability and efficiency of the screening device.

[0077] Furthermore, in this solution, the spacing between the positioning slider 13 and the support shaft 11 is small, so the two screening plates 5 can only vibrate slightly, which will not reduce the screening effect of the screening plates 5, but on the contrary can improve the screening efficiency.

[0078] Furthermore, in the present solution, two screening plates 5 are driven to rotate simultaneously by one motor 9, without the need for another motor, thereby reducing the cost of the device and being more energy-efficient.

[0079] Working principle: When the device is in use, the metallurgical auxiliary materials to be screened are poured into the installation frame 2, and then screened through the two screening plates 5. The mesh holes of the upper screening plate 5 are larger than the mesh holes of the lower screening plate 5. When the metallurgical auxiliary materials with larger particles roll downward through the two inclined screening plates 5 and flow out of the installation frame 2 through the two flow grooves 3, the metallurgical auxiliary materials with larger particles are screened out, and the two screening plates 5 make the metallurgical auxiliary material particles falling from the installation frame 2 more uniform, and the screening effect and quality are better, thereby increasing the practicality of the screening device.

[0080] Furthermore, by screening through two screening plates 5 with different mesh sizes, the sizes of metallurgical auxiliary materials discharged on the left and right sides are different, and the metallurgical auxiliary materials can be screened in multiple stages, making the screened metallurgical auxiliary materials more practical, thereby increasing the practicality of the screening device.

[0081] Furthermore, when the motor 9 is started, the motor 9 starts and synchronously drives the support shaft 11, the mounting block 14 and the positioning slider 13 to rotate synchronously. The rotation of the positioning slider 13 synchronously drives the fixed block 7 to perform a small reciprocating rotation around the fixed shaft 4 on the left side. Driven by the chain 8 and the two sprockets 6, the two fixed shafts 4 synchronously reciprocate, and then synchronously drive the two screening plates 5 to perform a small rotation around the two fixed shafts 4, thereby driving the metallurgical auxiliary materials of the screening plates 5 to vibrate. Starting the motor 9 can drive the two screening plates 5 to vibrate at the same time, thereby avoiding the metallurgical auxiliary materials from clogging the screening plates 5, making the screening efficiency higher and the screening effect better, thereby increasing the practicability and efficiency of the screening device.
